Bad mummy alert here as it happened a couple of days ago - he was playing in my sister's garden and fell on it. Complained a lot that day about it hurting, so I gave him nurofen.
The swelling and bruising (quite pronounced) is beneath the knuckle of the middle finger.
He hasn't been complaining about it since, unless I ask him to wiggle his fingers, which he can do a bit as the damage isn't actually on the knuckle.
What do you think? I'm kind of huffing and puffing at the idea of sitting in A&E (another bad mummy alert ).
